Description

Interface Summary

TransformerClient	A content handler can get a reference to a TransformState by implementing the TransformerClient interface.
TransformSnapshot	Deprecated. It doesn't look like this code, which is for tooling, has functioned propery for a while, so it doesn't look like it is being used.
TransformState	This interface is meant to be used by a consumer of SAX2 events produced by Xalan, and enables the consumer to get information about the state of the transform.

Class Summary

ClonerToResultTree	**For internal use only** Class used to clone a node, possibly including its children to a result tree.
Counter	**For internal use only** A class that does incremental counting for support of xsl:number.
CountersTable	**For internal use only** This is a table of counters, keyed by ElemNumber objects, each of which has a list of Counter objects.
DecimalToRoman	**For internal use only** Structure to help in converting integers to roman numerals
KeyIterator	**For internal use only** This class implements an optimized iterator for "key()" patterns, matching each node to the match attribute in one or more xsl:key declarations.
KeyManager	This class manages the key tables.
KeyRefIterator	**For internal use only** This class filters nodes from a key iterator, according to whether or not the use value matches the ref value.
KeyTable	**For advanced use only** Table of element keys, keyed by document node.
MsgMgr	This class will manage error messages, warning messages, and other types of message events.
NodeSorter	**For internal use only** This class can sort vectors of DOM nodes according to a select pattern.
QueuedEvents	This class acts as a base for ResultTreeHandler, and keeps queud stack events.
ResultNameSpace	**For internal use only** A representation of a result namespace.
SerializerSwitcher	This is a helper class that decides if Xalan needs to switch serializers, based on the first output element.
StackGuard	Class to guard against recursion getting too deep.
TransformerHandlerImpl	A TransformerHandler listens for SAX ContentHandler parse events and transforms them to a Result.
TransformerIdentityImpl	This class implements an identity transformer for and {@link javax.xml.transform.TransformerFactory#newTransformer().
TransformerImpl	**For advanced use only** This class implements the Transformer interface, and is the core representation of the transformation execution.
TrAXFilter
TreeWalker2Result	**For internal use only** Handle a walk of a tree, but screen out attributes for the result tree.
XalanProperties	XalanProperties defines the features understood by Xalan.
XalanTransformState	Before the serializer merge, the TransformState interface was implemented by ResultTreeHandler.

Package org.apache.xalan.transformer Description

In charge of run-time transformations and the production of result trees.

TransformerImpl implements the Transformer interface, and is the core representation of the transformation execution.

For each node in the XML source, TransformerImpl uses the StylesheetRoot and underlying XSLT schema to determine which template to apply: one of the templates in the StylesheetRoot, a default template rule as specified in the XSLT spec, or none.

The Transformer works with org.apache.xalan.transformer.ResultTreeHandler to forward the SAX events produced by the transformation to the appropriate output ContentHandler.

To the degree possible, the parsing of the XML source and application of the Templates object to that source are performed concurrently in separate threads. When necessary, the Transformer waits for the parse events that must be in place before a given template may be applied.
